Tercio

A Tercio is a traditional Spanish military formation from the 16th and 17th centuries, consisting of a flexible, highly disciplined group of infantry soldiers. It typically combined pikemen, who protected against cavalry, and musketeers, who provided ranged firepower, arranged in a coordinated structure. The Tercio was innovative for its time, offering a balanced and resilient fighting unit that could adapt to different battlefield situations. Its success made it a formidable and influential military organization during the Spanish Empire's dominance in Europe.
